Answer: Discounted function will be

Step-by-step explanation:
Since we have given that
Initial cost of solar energy = $9000
Average annual cost of heating a home with solar energy = $200
Rate of discount he received on the total cost = 25%
Let the number of year will be t
According to question, we need to write a discounted cost as a function of number of years.
So, our function becomes,

Hence, discounted function will be

Answer: 58
Step-by-step explanation:
From 10 AM to 1 PM the numbers are 161, 368, 842, and 1918
So now we find the difference between the numbers.
368 - 161 = 207
842 - 368 = 474
1918 - 842 = 1076
now it asked for the average so you add them together then divide by 3
which is (207+474+1076)/3 = 585.66666666....
Then it says to round to the nearest integer which is 586
